Reload with a DHCP Server Offer Without a DNS Server

Reload the Dell Networking OS on a switch using a preconfiguration script.

To reload the Dell Networking OS on a switch using a preconfiguration script, the following must be true:

• BMP is enabled.

• The download of the script is from an external server and the location is specified in the DHCP offer.

• The first line of the script contains one of the following:

#!/usr/bin/expect

#!/usr/bin/tclsh

#!/usr/bin/zsh

• If you installed the SmartScripts package, the Dell Networking OS also supports preconfigurated

scripts in Perl, Python, and Ruby.

#!/usr/pkg/bin/perl

#!/usr/pkg/bin/python

• After the first line, but before the start of the script, the script contains the signature #/DELL-

NETWORKING.

• The preconfiguration script downloads instead of the configuration file.

• The preconfiguration script runs before applying the start-up configuration file.

• The preconfiguration script can use the Dell Networking OS CLI commands using the f10do utility.

• When the preconfiguration script completes, the start up configuration file automatically applies.

If a preconfiguration script file downloads successfully, the following SYSLOGs display:

00:03:07: %STKUNIT0-M:CP %BMP-2-BMP_DOWNLOAD_START: The config

file download has started.

00:03:19: %STKUNIT0-M:CP %BMP-5-BMP_DWNLD_FILE_IS_SCRIPT_FILE:

download is successful.

00:03:21: %STKUNIT0-M:CP %BMP-5-BMP_PRE_CONFIG_SCRIPT_BEGIN:
